Technical Information

Manufacturer: Citroën
Model: Citroën Xsara Picasso (up to 2004) — Rear Left (Driver’s Side)
Product Codes: 9631564080, 89300250, 6350N0
Additional Numbers: 6350.N0

Function And Application

The tail light assembly houses stop, tail/position and indicator lighting elements and provides the correct optical alignment required for road safety and legal compliance. It is manufactured to match the original lens geometry and mounting points, ensuring proper sealing against water and vibrations when installed correctly.

Replacement Notes — How To Replace

Suitable for professional fitment or experienced DIY installers. General replacement steps:

• Open the rear hatch and remove the inner trim panel or access cover to reach the lamp fasteners.
• Unscrew or unclip the fasteners securing the lamp assembly and carefully pull the unit outward a few centimeters.
• Disconnect the electrical connector and remove the lamp from the body.
• Fit the new lamp ensuring the sealing surface is clean and undamaged, reconnect the electrical plug and secure the fasteners.
• Restore the interior trim and check all light functions (tail, stop, indicator) before returning the vehicle to service.

Recommended Tools And Tips

Common hand tools are sufficient: screwdrivers or socket set to remove fasteners, trim tools to avoid damaging panels, and a clean cloth to prepare sealing surfaces. After installation verify bulb seating and connector contact. Replace faulty bulbs or corroded sockets at the same time to prevent intermittent faults.

Why This Part Commonly Fails

Tail light failures on older Xsara Picasso models are usually caused by one or more of the following:

• Water ingress and condensation leading to corrosion of bulb holders and connectors.
• Impact damage to the lens or mounting tabs from minor collisions.
• Age-related degradation of internal seals and gaskets allowing moisture entry.
• Wear or corrosion of electrical contacts causing intermittent or non-functional lamps.

Installation Recommendations

Handle the new lamp by the housing and avoid touching bulbs with bare hands. Ensure mating surfaces are clean and dry and that the lamp is seated evenly before tightening fasteners. If connector terminals show corrosion, clean or replace them to ensure a reliable electrical connection. Test all light functions after installation and secure any loose wiring to prevent chafing.

Function

The socket secures the bulb(s) in the rear left lamp cluster and provides the electrical connection between the vehicle wiring harness and the bulb filaments. Proper seating and contact integrity are essential for consistent lighting performance across tail, stop, and indicator functions.

Common Failure Reasons

Typical causes of socket failure include corrosion of metal contacts due to moisture ingress, heat damage from incorrect or overloaded bulbs, brittle or cracked plastic from aging and vibration, and contact wear from repeated bulb replacements. Water penetration and damaged sealing around the lamp assembly accelerate deterioration and cause intermittent or complete loss of lighting functions.

Installation Recommendations

1. Prepare Work Area: Park vehicle on a level surface, engage handbrake and ensure good lighting.
2. Safety First: Disconnect the battery negative terminal before working on exterior lighting to reduce risk of short circuits.
3. Access Tail Lamp: Open the tailgate/boot and remove the interior trim or fasteners securing the tail light assembly.
4. Remove Lamp Assembly: Unscrew/remove the tail light unit and carefully pull it out to access the bulb holder.
5. Replace Socket: Twist or unclip the old bulb holder from the lamp cluster (depending on design), unplug the wiring connector and install the new socket. Ensure correct orientation and secure locking tabs.
6. Check Seals: Inspect lamp seals and gaskets; replace or reseal if signs of water ingress are present to prevent future corrosion.
7. Electrical Check: Reconnect the battery, test all light functions (tail, brake, indicator) before reassembly.
8. Final Assembly: Refit the lamp assembly and interior trim, torque fasteners to manufacturer recommendations and verify proper fitment.

Additional Tips: Use the correct bulb type and wattage for the vehicle, and consider applying a small amount of dielectric grease to contacts to slow corrosion. Bulbs Are Not Included.

Why Replace This Part

Replacing a worn or damaged socket restores reliable illumination and electrical safety. Symptoms that indicate replacement include flickering lights, intermittent function, visible corrosion or melting at the socket, or loose fit of the bulb in the lamp cluster.
